This study aims to determine if using lung ultrasound to guide personalized positioning for ventilated newborns is more effective than standard repositioning at preventing ventilator-associated pneumonia.
This research study is testing a new strategy to help prevent Ventilator-Associated Pneumonia(VAP) in newborns who need a breathing machine (mechanical ventilator). VAP is a serious lung infection that can sometimes occur in the hospital.We are using abedside Lung Ultrasound (LUS). This is a safe, painless, and radiation-free imaging tool. It allows doctors to see how well different parts of a baby's lungs are inflated in real-time, much like a "window" into the lungs.Based on the lung ultrasound pictures,our healthcare team will create a personalized positioning plan for the baby (for example, placing them more on their side or on their tummy). The goal is to use gravity to help open up the lungs and drain any fluid, which may lower the risk of infection. We will compare this new method to the standard practice of turning babies every two hours.We believe this personalized,evidence-based care strategy could be more effective in preventing pneumonia. It may potentially help babies get off the breathing machine sooner and reduce their time in the neonatal intensive care unit (NICU).Lung ultrasound is a well-established and safe bedside procedure.This study has been carefully reviewed and approved by the hospital's Ethics Committee. All procedures will be performed by trained doctors and staff, with the baby's safety and comfort as our top priority.

| standard positioning management | Behavioral | Infants in the control group had their positions adjusted every two hours, alternating between supine, left lateral, right lateral, and prone positions.The head of the bed should be elevated 15°-30° with the body in a slightly flexed position-hips aligned along the midline, shoulders slightly forward, head centered, and arms free to move. Position adjustments should only be made when vital signs are stable and resuscitation is delayed, or when adjusting the ventilator, administering IV fluids, or managing deep sleep. If heart rate fluctuates more than 20 beats per minute or SpO₂ drops below 90% (excluding airway obstruction), the interval between position adjustments should be extended to 3-4 hours. This group did not undergo ultrasound evaluation. |
| Measure | Description | Time Frame |
|---|---|---|
| Incidence of ventilator-associated pneumonia in neonates | Pneumonia that occurs 48 hours after mechanical ventilation (MV) and 48 hours after extubation is an important type of Hospital-acquired pneumonia (HAP), in which pneumonia that occurs within MV≤4 days is early-onset VAP, and pneumonia that occurs within MV ≥5 days is late-onset VAP. | From randomization until VAP diagnosis, successful extubation, or death, whichever occurs first, assessed up to 100 days. |
| Measure | Description | Time Frame |
|---|---|---|
| feeding intolerance in newborns | Incidence of feeding intolerance at any level (mild+severe) | From the beginning of enteral feeding to the successful establishment of full enteral feeding, discharge or death. The evaluation will last until the end of the study, and the longest evaluation period for each participant is expected to be 100 days. |

This study plans to share the collected individual participant data after de-identification.Specifically, it includes: demographic data (gestational age, birth weight, etc.), baseline characteristics, data related to VAP diagnostic criteria, lung ultrasound results, position adjustment records, mechanical ventilation duration, and all primary and secondary endpoint data (feeding intolerance, pulmonary hemorrhage, new intracranial hemorrhage, mortality rate, hospitalization days in NICU, etc.).
The data will be provided within 6 months after the publication of the main results of this study, and the data will be shared for at least 5 years.
To provide researchers who provide research proposals with rigorous methodology and clear scientific objectives for achieving the research objectives in the approved proposals. It usually includes meta-analysis of individual participant data, verification of results, or exploration of new scientific hypotheses that conform to the original research ethical framework.The proposal should be submitted to: liangzhenyu0823@163.com (please note: please replace this with the official contact email you wish to use).
To gain access, the applicant needs to sign a data use agreement. The research steering committee of this study will review the scientific value and methodological rigor of the proposal.

| Lung Ultrasound Guided Localization | Behavioral | In addition to routine care, two LUS assessments are conducted at fixed times daily (08:00 and 18:00) to guide individualized position adjustments by monitoring regional ventilation.①If unilateral atelectasis or pulmonary edema is detected, the patient should first be maintained in dependent lateral position for approximately 1 hour, then transition to the contralateral or prone position for 3 hours.②For lesions previously managed by the department, the prone position duration is reduced to 1 hour, while supine or lateral positions are extended to 3 hours. ③For posterior lesions, the supine or lateral position should be limited to 1 hour, while the prone position should be extended to 3 hours.④Resume the standard two-hour shift system once the symptoms or edema have subsided.If SpO₂ remains persistently below 90% (excluding operational or feeding disturbances), the respiratory rate increases by more than 20 breaths per minute from baseline, an additional LUS evaluation is required. |
